袋鼠式護理法Kangaroo Care是母親將早產嬰兒抱在身上以肌膚直接接觸嬰兒並提升其體溫

袋鼠式護理法Kangaroo Care是母親將早產嬰兒抱在身上以肌膚直接接觸嬰兒並提升其體溫(有別於躺在早產房嬰兒床)之作法;臨床研究發現袋鼠式護理法改變了早產嬰兒的HRV及其對疼痛的反應

BACKGROUND: Heel stick is the most common painful procedure for preterm infants in neonatal intensive care units. Resultant pain causes adverse physiological effects in major organ systems. Kangaroo Care (KC), involving mother-infant skin-to-skin contact is a promising analgesic for infant pain; however, the effect of KC on the autonomic nervous system's response to pain is unknown. AIM: To determine if KC results in improved balance in autonomic responses to heel stick pain than the standard method where infants remain in an incubator care (IC) for the heel stick. STUDY DESIGN: A randomized cross-over trial. SUBJECTS: Fourteen preterm infants, 30-32 weeks gestational age and less than 9 days postnatal age. OUTCOME MEASURES: Infant behavioral state, heart rate, heart rate variability (HRV) indices including low frequency (LF) and high frequency (HF) power, and the LF/HF ratio measured over Baseline, Heel Warming, Heel Stick, and Recovery periods in KC and IC conditions. RESULTS: HRV differences between KC and IC were that LF was higher in KC at Baseline (p<.01) and at Heel Stick (p<.001), and HF was higher in KC at Baseline than in the IC condition (p<.05). The LF/HF ratio had less fluctuation across the periods in KC than in IC condition and was significantly lower during Recovery in KC than in IC (p<.001). CONCLUSIONS: Infants experienced better balance in response in KC than IC condition as shown by more autonomic stability during heel stick. KC may be helpful in mediating physiologic response to painful procedures in preterm infants.
